2003 CR-V Check Engine Light
 

My 2003 CR-V (54,000 miles) has had the Check Engine Light come on
sporadically over the last 4-5 months. It's come on four different times.
Each time it has come on, it has stayed on for about 3 or 4 trips, and by
about the fifth time I turn on the car after I first saw the light go on,
it's off. The first time this happened was in May, and it was a long time
before it happened again, but it's now happened two times this month. Any
idea why this would be happening. Nothing seems to be wrong with the car at
all -- in fact it was just in for routine maintainence.

Thanks for any info.
